Abstract

By using a semi-efficient vulcanization system, Alkanolamide (ALK) was incorporated into kaolin-filled natural rubber compound at 1.0; 3.0; 5.0 and 7.0 parts per hundred rubber (phr). An investigation was carried out to examine the effect of ALK on tensile properties of the kaolin filled-natural rubber compound. It was found that ALK exhibited higher tensile modulus, tensile strength, and elongation at break up to 5.0 phr of ALK loading and then decreased with further increasing of ALK loading. Crosslink density measurement proved that 5.0 phr loading of ALK in the kaolin-filled natural rubber system exhibited greatest tensile properties due to its highest crosslink density formation.

Abstract

By using a semi-efficient sulphur accelerated vulcanization system, an investigation of the effect of alkanolamide on cure characteristics and hardness properties of kaolin-filled natural rubber compounds was carried out. Alkanolamide was synthesized from Refined Bleached Deodorized Palm Stearin (RBDPS) and diethanolamine. Alkanolamide was incorporated into the kaolin filled-natural rubber compound at 1.0; 3.0; 5.0 and 7.0 Parts per-Hundred RubbeR (phr). It was found that alkanolamide gave shorter scorch time and cure time. Alkanolamide also exhibited higher torque different, crosslink density, and hardnessup to 5.0 phr and then decreased with further increasing the loading of alkanolamide.
